Introduction: Ultrasonography is cheap, non-invasive, reliable, fast method of diagnostic investigation in the measurement of liver size. Normal range of liver size helps to diagnose hepatomegaly sonologically which may be clinically inapparent. Thus warrants further clinical evaluation and other investigations for the prevention of major hepatic comorbidities.Methods:  A  prospective, cross-sectional study was conducted on 400 adults with sonographic findings unrelated to liver pathologies. The liver was measured in right midclavicular line from hepatic dome to lower hepatic margin.  The correlation between liver size and age, sex, weight, height, body mass index (BMI), and body surface area(BSA) was calculated.  The data were properly analyzed in  SPSS version 20 software.Results: Out of 400 patients, a male: female ratio of 1:1.25, and the age group was ranging from 20 years to 83 years with a mean age of 48.10±14.86 years were included. The mean liver length in males was  15.05 ± 0.27 cms,  females were 14.32 ± 0.29 cms and the total population was 14.73 ±0.46 cms. There was a strong statistically significant correlation between liver size and height, weight whereas the correlation between liver span and BSA was moderate to weak but significant.  Similarly, there was a weak but significant correlation between liver size and BMI with no significant association between liver size and age.Conclusion:  Accurate assessment of liver size is of utmost importance in the evaluation of suspected hepatic pathologies.
超声检查是一种廉价、无创、可靠、快速的肝脏大小测量诊断方法。肝大小正常范围有助于超声诊断临床上不明显的肝肿大。因此,需要进一步的临床评估和其他研究来预防主要的肝脏合并症。方法:对400名成人进行前瞻性横断面研究,超声检查结果与肝脏病变无关。在右锁骨中线自肝穹窿至肝下缘处测量肝脏。计算肝脏大小与年龄、性别、体重、身高、体重指数(BMI)和体表面积(BSA)的相关性。采用SPSS 20软件对数据进行分析。结果:400例患者中,男女比例为1:1.25,年龄20 ~ 83岁,平均年龄48.10±14.86岁。雄性平均肝长15.05±0.27 cm,雌性平均肝长14.32±0.29 cm,种群平均肝长14.73±0.46 cm。肝大小与身高、体重有较强的统计学意义相关,而肝跨度与BSA的相关性为中至弱但显著。同样,肝脏大小与BMI之间存在微弱但显著的相关性,而肝脏大小与年龄之间没有显著相关性。结论:准确评估肝脏大小对诊断疑似肝脏病变至关重要。

Introduction: Among various imaging modalities useful in diagnosis of  cervical lymphadenopathies, Color Doppler ultrasound (CDUS) is useful to evaluate and determine the presence of vascularity, resistance, direction, and velocity of blood flow in lymph nodes. It can determine the morphological and vascular nature of lymphadenopathies which will further help in the differentiation between benign and malignant nodes.Methods: This study was conducted on 61 patients referred to the Department of radiodiagnosis and imaging of BiratMedcical College for an ultrasound of cervical lymphadenopathy. These patients had subsequently undergone FNAC examination. Color Doppler sonographic procedures were done with an 11L linear probe with a frequency of 4.5-12MHz and CDUS evaluation of lymph nodes for Resistive Index and Peak systolic velocity were carried out and correlated with FNAC findings.Results: Among 61 lymph nodes, 52 were benign and 9 were malignant in the Color Doppler study where the final diagnosis by FNAC showed 53 benign and 8 malignant nodes. RI above the cutoff value of 0.5 had 83.3% sensitivity, 79.6% specificity, 50% PPV and 95.1% NPV. PSV above the cutoff value of 16cm/sec had 66.6% sensitivity, 95.9% specificity, 80.0% PPV and 92.2% NPV with diagnostic accuracy of 91.8%.Conclusion: Morphological features of the nodes such as shape, absence of echogenic hilum, abnormal vascular pattern, and Doppler indices cutoff values of 0.5 and 16cm/s respectively for RI and PSV were sensitive and specific for the diagnosis of malignant lymph nodes.
简介:在诊断颈部淋巴结病的各种成像方式中,彩色多普勒超声(CDUS)可用于评估和确定淋巴结内血管性、阻力、血流方向和速度的存在。它可以确定淋巴结病变的形态和血管性质,这将进一步帮助区分良恶性淋巴结。方法:本研究对61例转诊至birat医学院放射诊断与影像科行宫颈淋巴结病超声检查的患者进行分析。这些患者随后接受了FNAC检查。使用频率为4.5-12MHz的11L线性探头进行彩色多普勒超声检查,CDUS评估淋巴结的电阻指数和峰值收缩速度,并将其与FNAC检查结果相关联。结果:61个淋巴结中,52个为良性,9个为恶性,FNAC最终诊断为良性53个,恶性8个。高于临界值0.5的RI敏感性为83.3%,特异性为79.6%,PPV为50%,NPV为95.1%。PSV高于16cm/sec的敏感性为66.6%,特异性为95.9%,PPV为80.0%,NPV为92.2%,诊断准确率为91.8%。结论:淋巴结形态、门部无回声、血管形态异常,RI和PSV的多普勒指数截止值分别为0.5和16cm/s,对恶性淋巴结的诊断具有敏感性和特异性。

Introduction: The knee joint is the space between the femoral and tibial condyles. The tibiofemoral articulations are separated by articular cartilages and menisci; with little contributions from cruciate ligaments. These are collectively seen on a radiograph as a radiolucent area between the bony tibial and femoral condyles. This study was conducted to measure the normal knee joint space in patients referred for X-Ray to the Department of Radiology of a tertiary care hospital. Methods: This descriptive cross-sectional study was performed from 1st January to 1st April 2021 in the Department of Radiology and Imaging, Tribhuvan University Teaching Hospital (TUTH). A total of 157 patients were involved. The radiographic joint space width in the knee joint was measured in both medial and lateral compartments of bilateral knees in correlation with age and gender. Results: The mean right medial, left medial, right lateral, and left lateral spaces for females were 0.25±0.08 cm, 0.23±0.09 cm, 0.49±0.10 cm, and 0.49±0.29 cm respectively. Similarly, the mean right medial left medial, right lateral, and left lateral spaces for males were 0.26±0.07 cm, 0.10±0.09 cm, 0.18±0.09 cm, and 0.17±0.08 cm respectively. There was a strong positive correlation between both right and left joint spaces about age. Conclusion: The radiographic reference values for the joint space width were obtained, showing a positive correlation with age and no significant gender variations in bilateral knees.
膝关节是股骨髁和胫骨髁之间的间隙。胫股关节被关节软骨和半月板分开;十字韧带的作用很小。在x线片上,这些都是胫骨和股骨髁之间的一个透光区域。本研究旨在测量某三级医院放射科接受x光检查的患者的正常膝关节间隙。方法:本描述性横断面研究于2021年1月1日至4月1日在特里布万大学教学医院(TUTH)放射与影像科进行。共涉及157例患者。测量双侧双膝内侧和外侧关节室膝关节的x线关节间隙宽度,与年龄和性别相关。结果:女性右侧内侧、左侧内侧、右侧、左侧间隙平均分别为0.25±0.08 cm、0.23±0.09 cm、0.49±0.10 cm、0.49±0.29 cm。男性右侧内侧、左侧内侧、右侧外侧和左侧外侧的平均间距分别为0.26±0.07 cm、0.10±0.09 cm、0.18±0.09 cm和0.17±0.08 cm。左右关节间隙与年龄呈正相关。结论:获得了双膝关节间隙宽度的影像学参考值,双膝关节间隙宽度与年龄呈正相关,无明显性别差异。

Introduction: Skeletal tuberculosis accounts for approximately two percent of all infected tuberculosis (TB). Magnetic resonance imaging (MRI) due to its inherent soft tissue contrast is a very good tool to diagnose the condition and look for its extent and deformities. This study aims to study the MRI findings in a patient with diagnosed case of spinal tuberculosis.Methods: The study was carried out in a referral diagnostic imaging center in western Nepal. All MRI studies of the spine performed in a patient with diagnosed spinal tuberculosis during the study period were included in the study. Patients lacking microbiological or pathological diagnoses of spinal tuberculosis were excluded from the study.Results: A total of 70 patients were included in the study. The mean age of the patients was 45.6 ± 16.8 years. All patients in the study had a spondylodiscitis pattern of involvement. Single intervertebral disc and adjacent vertebrae were involved in 85.7% and multiple contiguous vertebrae and IV discs were involved in 14.3% of cases. Gibbus deformity was seen in 17.1% of cases. Pre/paravertebral and Epidural collections were seen in 95.7% and 72.9% of patients respectively, whereas psoas abscess was seen in 28.6% of patients. Cord compression with myelopathy was seen in 8.6% of patients. Involvement of posterior elements was seen in 27.1% of patients.Conclusion: MRI is an excellent tool to see the extent, deformity, and abscess in spinal tuberculosis. Most patients with tuberculosis present late with collections and deformities.
导言:骨结核约占所有感染结核(TB)的2%。磁共振成像(MRI)由于其固有的软组织对比,是一种很好的诊断疾病和寻找其程度和畸形的工具。本研究旨在研究诊断为脊柱结核患者的MRI表现。方法:研究在尼泊尔西部的转诊诊断成像中心进行。在研究期间诊断为脊柱结核的患者进行的所有脊柱MRI检查均纳入研究。没有微生物学或病理诊断为脊柱结核的患者被排除在研究之外。结果:共纳入70例患者。患者平均年龄45.6±16.8岁。研究中的所有患者都有脊柱椎间盘炎的累及模式。累及单个椎间盘及相邻椎体占85.7%,累及多个相邻椎体及IV椎间盘占14.3%。17.1%的病例出现Gibbus畸形。95.7%的患者出现椎前/椎旁积液,72.9%的患者出现硬膜外积液,28.6%的患者出现腰肌脓肿。8.6%的患者出现脊髓受压伴脊髓病。27.1%的患者累及后路因素。结论:MRI是观察脊柱结核的范围、畸形和脓肿的良好工具。大多数结核患者出现较晚,伴有积液和畸形。

Midline cystic neck swellings are often seen in younger patients and may have several causes.  Sonography is the initial imaging modality followed by a Computer Tomography (CT) scan with MRI being reserved as a problem-solving tool or for preoperative extent evaluation. Pathology usually uses fine-needle aspiration cytology to confirm the diagnosis. We report a case where a cold abscess presenting as cystic midline neck swelling in a young patient, was misinterpreted as an infected thyroglossal cyst on sonography. The presence of lesions consistent with pulmonary tubercular infection helped clinch the diagnosis on the CT scan. This case also highlights the fact that whenever possible a common cause should be sought for different lesions occurring simultaneously.
中线囊性颈部肿胀常见于年轻患者,可能有多种原因。超声检查是最初的成像方式,其次是计算机断层扫描(CT)扫描,MRI保留作为解决问题的工具或用于术前范围评估。病理学通常使用细针穿刺细胞学来确诊。我们报告一个年轻患者的冷脓肿表现为囊性中线颈部肿胀,超声检查时被误认为是感染甲状腺舌囊肿。与肺结核感染相符的病变的存在有助于确定CT扫描的诊断。这个病例也强调了这样一个事实,即只要可能,就应该寻找同时发生的不同病变的共同原因。

Introduction: The goal of this study is to find the sensitivity and specificity of High resolution computed tomography (HRCT) of the chest in diagnosing COVID-19 infection using Reverse Transcription Polymerase Chain Reaction (RT-PCR) as a gold standard. Methods: All patients clinically suspected of having COVID 19 infection who had undergone both RT PCR test and HRCT chest were included in the study. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy of HRCT chest in diagnosing COVID 19 infection were calculated considering RT-PCR as the gold standard test. Results: A total of 100 patients were included in the study. The mean age was 55.68 years. HRCT chest showed 92.85 % sensitivity, 68.75 % specificity, 93.97 % PPV, 64.7 % NPV and 89 % diagnostic accuracy in the detection of COVID-19 infection. Conclusion: HRCT scan of the chest shows high sensitivity and specificity for the diagnosis of COVID-19 pneumonia. It is a fast diagnostic test and also helps in grading the severity of pneumonia thus in further management.

Introduction: Cigarette smoking is a well-known etiology for chronic musculoskeletal system disorders, like osteoarthritis, affecting the distal femoral cartilages. However, recent studies show protective effects of smoking against osteoarthritis. Ultrasound is an easily accessible and reliable imaging tool for the evaluation of the cartilages, measurement of their thickness, and tissue stiffness. This study seeks to objectively show the effects of smoking by affecting their knee joints’ cartilage and clarify whether it has a chondroprotective effect, or support the usual evidence that smoking is harmful at any cost.Methods: This prospective cross-sectional study compares the thickness and elasticity of distal femoral cartilage in heavy, ordinary smokers and non-smokers using B-mode scanning and real-time strain elastographic technique of ultrasound respectively. Results: Among 377 individuals with a mean age of 27.66 years, male predominance (70 %) and mean Body Mass Index (BMI) of 24.55, a higher proportion (50 %) of volunteers were ordinary smokers (pack years <20). Elasticity strain ratios were found to be significantly lower in heavy smokers in both sides’ distal femoral cartilages except in right lateral cartilage (p = <0.001) using Fisher’s exact test. Significantly lower thickness was noted in both cartilages of the right side (p <0.001) and left lateral cartilage (p = 0.001) among heavy smokers. After adjusting for the effects of age, sex, BMI, and occupation using one-way ANOVA, similar results were obtained. Conclusions: Heavy cigarette smoking causes degradation of distal femoral cartilages by decreasing their thickness and elasticity.
简介:吸烟是众所周知的慢性肌肉骨骼系统疾病的病因,如骨关节炎,影响股骨远端软骨。然而,最近的研究表明,吸烟对骨关节炎有保护作用。超声是一种容易获得和可靠的成像工具,用于评估软骨,测量其厚度和组织刚度。这项研究旨在客观地展示吸烟对膝关节软骨的影响,并阐明吸烟是否有保护软骨的作用,或者支持吸烟不惜任何代价都有害的通常证据。方法:本前瞻性横断面研究分别采用b型扫描和超声实时应变弹性成像技术比较重度吸烟者、普通吸烟者和非吸烟者股骨远端软骨的厚度和弹性。结果:在377名平均年龄27.66岁、男性占多数(70%)、平均身体质量指数(BMI)为24.55的志愿者中,普通吸烟者(包年<20)的比例较高(50%)。使用Fisher精确检验发现,除右侧外侧软骨外,重度吸烟者两侧股骨远端软骨的弹性应变比显著降低(p = <0.001)。在重度吸烟者中,右侧软骨(p <0.001)和左侧外侧软骨(p = 0.001)的厚度明显较低。在使用单因素方差分析调整了年龄、性别、BMI和职业的影响后,得到了类似的结果。结论:重度吸烟可导致股骨远端软骨的厚度和弹性降低。

Introduction: The new coronavirus disease -19 (COVID-19) is caused by SARS-CoV2 strain of coronavirus. The Computed tomography (CT) severity index is a scoring system used to assess the lung changes and involvement by COVID-19 based on approximate estimation of pulmonary involved areas. This study was done to identify the spectrum of CT chest findings and CT severity index in COVID-19 infection and its correlation with age and gender. Methods: Patients with COVID-19 infection with positive PCR results and positive pulmonary CT findings were included in the study. All these patients underwent high-resolution computed tomography (HRCT) of the chest. The CT scan severity score in all of these patients was calculated and the results were analyzed by SPSS version 21. Results: A total of 104 patients with confirmed COVID-19 infection were included in this study. There were 59 males (56.73%) and 45 females (43.3%) in this study. There was a higher chest severity score in males compared to females. However, there was no significant correlation between the age and CT chest severity score. Conclusion: HRCT chest can help in the early identification of the patients who need intensive care. Early admission and intensive care of the patients with high CT severity scores may help to reduce the mortality of COVID-19 patients.
新型冠状病毒病-19 (COVID-19)是由冠状病毒SARS-CoV2株引起的。计算机断层扫描(CT)严重程度指数是一种基于肺部受累区域的近似估计来评估COVID-19肺部变化和受累程度的评分系统。本研究旨在确定COVID-19感染的CT胸部表现谱和CT严重程度指数及其与年龄和性别的相关性。方法:将PCR阳性、肺部CT阳性的COVID-19感染患者纳入研究。所有患者均行胸部高分辨率计算机断层扫描(HRCT)。计算所有患者的CT扫描严重程度评分,并使用SPSS version 21对结果进行分析。结果:共纳入104例确诊的COVID-19感染患者。男性59例(56.73%),女性45例(43.3%)。男性的胸部严重程度评分高于女性。然而,年龄与CT胸部严重程度评分无显著相关性。结论:胸部HRCT有助于早期识别需要重症监护的患者。CT严重程度评分高的患者尽早入院并进行重症监护可能有助于降低COVID-19患者的死亡率。

Skeletal hydatidosis results from deposition of the larval form of the Echinococcus, a genus of tapeworm. The incidence of bone disease is extremely low as most larvae are trapped by the liver and lung upon release of the embryo into the portal blood stream. Bone hydatid disease is often asymptomatic and its diagnosis is usually made at an advanced stage when lesions have become extensive. The interpretation of imaging studies can prove very confusing as there are no characteristic features and this often leads to misdiagnosis. We present a case of a 83 year-old man who was admitted to BPKIHS, Dharan complaining of pain and swelling in left hip.CT scan  showed lytic lesion in sacral vertebra involving  left sacroiliac joint and ilium and was falsely diagnosed as tuberculosis or  neoplastic in nature. The result of  FNAC concurred on an unexpected diagnosis of a hydatid cyst. This case illustrates that in the absence of  high index of suspicion for echinococcal infection, imaging findings of hydatid disease in bone mimic to those of other skeletal pathologies and can lead to misinterpretation.
骨包虫病是由绦虫属棘球绦虫的幼虫沉积引起的。骨病的发病率极低,因为大多数幼虫在胚胎释放进入门静脉血流时被肝脏和肺部捕获。骨包虫病通常是无症状的,它的诊断通常是在病变变得广泛的晚期做出的。由于没有特征性特征,影像学检查的解释可能非常混乱,这经常导致误诊。我们提出一例83岁的男子谁被承认BPKIHS, Dharan抱怨疼痛和肿胀在左髋关节。CT显示骶椎溶解性病变累及左骶髂关节及髂骨,误诊为结核或肿瘤。FNAC的结果与一个意想不到的诊断一致:包虫囊肿。该病例说明,在棘球蚴感染缺乏高怀疑指数的情况下,骨棘球蚴病的影像学表现与其他骨骼病理相似,可能导致误解。
